Investigation of the Effect of Weft Yarn Parameters on the Elasticity and Recovery Properties of Stretch Denim Fabrics

ABSTRACT

The aim of this study was to examine the effect of weft yarn parameters on the elasticity and recovery properties of stretch denim fabrics. For this purpose, frequently used denim fabric was taken as a reference point, and to study the elasticity, and dimensional change properties of the reference fabric, the production of new denim fabrics was designed with the use of different core yarns in the weft direction with different ratios. As a result, five different denim fabrics containing three different weft yarns with different sequences in Twill 3/1 Z weave type were produced. All fabric samples were prepared as half legs form and rinse washing, stone washing and stone+bleaching washing processes were applied. Elasticity, residual extension, and dimensional stability tests of the samples were performed, and the results were analyzed regarding the weft yarn properties and finishing processes. In addition to these tests, mass per unit area was examined to observe the weight changes of the fabrics due to shrinkage after washing. All tests were evaluated statistically. According to the analysis, it was found that the fabric performance was affected by the weft yarn type, and the different washing processes.

摘要

研究了纬纱参数对弹力牛仔布弹性和回复性能的影响. 为此, 以常用的牛仔布为参考点, 研究参考织物的弹性、尺寸变化特性, 设计了在纬纱方向使用不同芯纱、不同配比的新型牛仔布的生产工艺. 试验结果表明, 斜纹3/1z组织的三种纬纱的排列顺序不同, 织出五种不同的牛仔布. 所有织物样品制备成半支腿形式, 采用漂洗、石洗和石+漂洗工艺. 对试样进行了弹性、残余伸长和尺寸稳定性试验, 并对试验结果进行了分析. 除此之外, 我们还测试了织物的单位面积质量, 以观察织物在洗涤后由于收缩而引起的重量变化. 所有试验均进行统计学评价. 通过分析发现, 纬纱类型和不同的洗涤工艺对织物性能有一定的影响.
